Honda GC160 muffler cap?

#1
I have Honda CG160 on my DB30, runs great. I ordered and received the muffler cap to deflect the exhaust to one side. Received it today and has hole right in the middle, does absolutely nothing to deflect exhaust. :shrug:

I guess Honda has reasons to make it this way, have no idea why? I think I can fix it with a strip of sheet metal flashing, just wondering if any one knows why it was designed this way.

I know Briggs has a nice muffler cap that really does deflect the exhaust on their stock exhaust, thought I would get the same from Honda. :confused:
